  • salt to taste
  • 1 Tbsp. flour

Instructions

Tips & Substitutions

For a richer flavor, consider using garlic butter instead of regular butter. If you're out of dried mint, fresh mint or thyme can work well as alternatives. Ensure that the onions are of similar size for even cooking. If you prefer a bit of crunch, add a sprinkle of breadcrumbs on top before baking.

Serving Suggestions

Baked onions make a delightful side dish that pairs beautifully with grilled meats or roasted vegetables. Try serving them alongside a fresh salad or with a dollop of Spicy Cranberry Cheese for an extra flavor boost. They also complement vegetarian recipes well, making them a versatile addition to any meal.
